ELECTRONIC FUEL INJECTOR FOR 4-CYCLE V-TYPE MULTIPLE CYLINDER INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To uniformalize injection amount between cylinders by injecting fuel near the upper dead point of every cylinder in an electronic fuel injector for a 4 cycle V-type multiple cylinder internal combustion engine. CONSTITUTION:Intake air which has passed through a hot wire system air flow meter 3 built in an air cleaner 12 is sucked into an internal combustion engine 1 to be distributed to each cylinder. Signals of said air flow meter 3, a throttle valve opening sensor 10 and an ignition coil 4 are supplied to the input of a control unit 5 to control a fuel injection valve 2. Fuel is injected near the upper dead point of every cylinder. Namely, there is no difference of injection amount between the respective cylinders since fuel is injected under the same intake pressure in all cylinders.
